DynaFrax has been participating in several international R&D, industry and government projects. For information and references, please contact us.

THERMOQUAKE, Thermally induced seismicity and evolution of Forsmark spent nuclear fuel repository

This is a project funded by the Swedish Radiation Safety Authority (SSM). The project aimed at understanding and modelling of a thermally induced slip of the fracture system and long-term evolving seismicity in the rock mass for final disposal of spent nuclear fuel repository at Forsmark, Sweden. DynaFrax conducted 3D TM coupled modelling and fault dynamic rupture simulation and performed long-term safety assessment of the Forsmark repository.

DECOVALEX2019, Task B

The DECOVALEX (DEvelopment of COUpled models and their VALidation against EXperiments) project is an international research and model comparison collaboration, initiated in 1992, for advancing the understanding and modelling of coupled thermo-hydro-mechanical-chemical (THMC) processes in geological systems. DynaFrax joined Task B: Modelling the induced slip of fault in argillaceous rock.

DECOVALEX2023, Task G

This is the current and 8th phase of the project and runs from 2020 till 2023. DynaFrax joins and leads Task G, which aims at understanding of shear reactivation of pre-existing discontinuities for brittle host rocks as the results of coupled thermal(T), hydraulic(M), mechanical(M), and chemical(C) effects.

KEM-24, Effect of pressure maintenance by fluid injection on seismic risk

This is a project funded by the Ministry of Economic Affairs and Climate of the Netherlands, aiming at estimating the possible seismic risk in the Groningen gas field by fluid injection for pressure maintenance as a measure for mitigating the depletion-induced seismicity. DynaFrax performs a series of numerical modelling of fluid injection induced seismicity in the Groningen gas field model.

MiDAS, Geomechanical stress evolution modelling in eastern Taiwan

This is a project from the National Central University, Taiwan, aiming at understanding and estimation of stress evolution in northeastern part of Taiwan after the Hualien earthquake in 2018. DynaFrax performs 3D regional scale earthquake modelling and analyzes the stress field disturbed by the earthquake and estimates the evolution of stress field for seismic hazard assessment.

Earthquake induced changes in the hydrogeological condition of radwaste disposal site

This is a project funded by the Korea Radioactive Waste Agency (KORAD), aiming at understanding and modelling of seismically induced changes in the hydrogeological characteristics of the rock mass at the site for disposal of low and intermediate level radioactive wastes. DynaFrax performed a 3D modelling where the slip of the repository DFN was induced by seismic loading of 2016 Gyeong-Ju earthquake in Korea, and estimated the possible changes in the hydrogeological properties (permeability & conductivity) of the disposal site rock mass.

Long-term THMC coupled behaviors of radwaste disposal site

This is a project funded by KORAD, aiming at understanding and modelling of long-term changes in the geochemical and hydrogeological characteristics of the rock mass at the disposal site. DynaFrax, with the project partner Amphos21, performs THMC coupled modelling, and conducts assessment of long-term safety of the repository site.

Seismic safety of Engineered Barrier System (EBS)

This is a project funded by KORAD, aiming at understanding and modelling of integrity of the EBS of the surface disposal facility. DynaFrax performs safety assessment by conducting 3D modelling of seismic loading induced damage/failure of the EBS.
